Turning to FIG. 1 , an example operational environment for implementing aspects of the subject matter is depicted and referenced generally by designator 100. For instance, monitor device 130 may implement methods 500 and 600 of FIGS. 5 and 6 , respectively. The components shown in FIG. 1 are a few of the components that embodiments of the present invention may interact with during operation. Accordingly the components therein are described with an emphasis on function and in brief for the sake of simplicity. One skilled in the art will recognize that operational environment 100 is but one example of a suitable operational environment for implementing aspects of the invention. As such, system 100 is not intended to suggest any limitation as to the scope of use or functionality of the invention.

Operational environment 100 includes event detector 110, monitor device 130, server 140, and client device 160. Each of the components included in operational environment 100 are operatively coupled to each other as appropriate for carrying out their respective functions. For example, event detector 110 is interconnected with one or more event detectors (not shown) via a common physical medium (common interconnect 120) that is adapted to propagate interconnect signals among the event detectors. Also, monitor device 130, server 140, and client device 160 are configured to communicate data via network 150. In an embodiment, event detector 110 is incapable of communicating data via network 150. In an embodiment, operational environment 100 also includes switch 170 and router 180 to facilitate communication via network 170. In an embodiment, one or more of the functionalities described below with respect to monitor device 130 may be implemented in switch 170, router 180, or a combination thereof. Various embodiments of aspects of monitor device 130 are further described herein below with respect to FIGS. 13A-13C.

Event detector 110 is configured to detect at least one event associated with a physical environment proximate to event detector 110's location. Examples of suitable devices for implementing event detector 110 include a motion detector, a gas detector, a radio frequency (“RF”) detector, a smoke detector, a presence detector, and the like. Event detector 110 detects the at least one event using sensor data indicative of a physical quantity associated with the physical environment. The sensor data that event detector 110 uses to detect the at least one event is provided by one or more sensors associated with event detector 110. In an embodiment, the one or more sensors include an internal sensor contained within a housing of event detector 110. Responsive to detecting the at least one event, event detector 110 causes an alert indicator associated with event detector 110 to generate a sensory notification that alerts nearby observers of the detected event. As used herein, “sensory notification” refers to sensory stimuli capable of being perceived by one or more senses of an observer.

Event detector 110 is further configured to forward an interconnect signal to the one or more event detectors via common interconnect 120. In an embodiment, an interconnect signal corresponds to an alert

The interconnect signal configured to inform the one or more event detectors that event detector 110 has detected an event. In operational environment 100, interconnect signals are propagated among the event detectors to enable each of the event detectors to generate a sensory notification when any single event detector (e.g. event detector 110) detects an event. That is, each event detector among the one or more event detectors utilize interconnect signals to communicate to the remaining event detectors that an event was detected. Examples of interconnect signals are discussed below with respect to FIGS. 11-12 . Accordingly, event detector 110 is configured to cause the alert indicator to generate a sensory notification in response to receiving an interconnect signal via common interconnect 120.

Monitor device 130 is generally configured to monitor interconnect signals associated with event detector 110 by interfacing with common interconnect 120. In an embodiment, monitor device 130 directly interfaces with common interconnect 120. For example, monitor device 130 may be directly hardwired to common interconnect 120. In an embodiment, monitor device 130 indirectly interfaces with common interconnect 120 thereby electrically isolating monitor device 130 from common interconnect 120. For example, monitor device 130 may indirectly interface with common interconnect 120 using optical, inductive, capacitive, or similar isolation coupling techniques.

Monitor device 130 is further configured to generate interconnect data based at least in part on interconnect signals propagating along common interconnect 120. As used herein “interconnect data” refers to information about an event detector inferred, in part, from interconnect signals propagating on a common physical medium interconnecting the event detectors. In an embodiment, interconnect data includes information about event detector 110's alarm status. For example, interconnect data may include information indicating that event detector 110's alarm status is activated (i.e. event detector 110 detected an event), non-activated (i.e. event detector 110 has not detected an event). In an embodiment, the interconnect data includes further information about the event detected by event detector 110. For example, what type of event was detected, where the event was detected, and the like. As another example, when multiple event detectors are interconnected via interconnect 120, interconnect data may include information about which event detector among the multiple event detectors detected an event.

In an embodiment, interconnect data includes information about an event detector's operational status. For example, interconnect data may include information indicating that event detector 110's operational status is fully functional, degraded functionality, non-functional, and the like. In an embodiment, monitor device 130 generates interconnect data that includes identifying information about event detector 110. For example, monitor device 130 may infer event detector 110's manufacturer, model number, configuration, and the like.

In an embodiment, monitor device 130 is configured to generate interconnect metadata based at least in part on secondary data associated with the interconnect data. As used herein “interconnect metadata” refers to information providing context to interconnect data that monitor device 130 obtains from sources external to the common interconnect. For example, interconnect metadata may include time stamp information, sensor data provided by sensors unassociated with event detector 110, a confidence value associated with current interconnect data derived from previous interconnect data, and the like.

Monitor device 130 is further configured to communicate any combination of interconnect data and interconnect metadata (if available) via network 150 to one or more devices for further processing. For example, monitor device 130 may communicate any combination of interconnect data and interconnect metadata to server 140 for further processing. In an embodiment, monitor device 130 communicates such data via network 150 on a continuous basis. In an embodiment, monitor device 130 communicates such data via network 150 on a periodic basis. In an embodiment, monitor device 130 receives a predefined interval (e.g. every 5 minutes, 12 minutes, hour, 2 hours, etc.) for the periodic basis from a remote client (e.g. server 140 or client device 160). In an embodiment, monitor device 130 communicates such data via network 150 in response to determining a predefined criterion is met. Examples of predefined criterion include event detector 110 detecting an event, event detector 110's operational status changes, a confidence value associated with current interconnect data falls below a predetermined threshold, and the like. In an embodiment, monitor device 130 communicates such data in response to a request from a remote device.

Server 140 provides computing resources to remote clients (e.g. monitor device 130 and client device 160) via network 150. Server 140 may be implemented using one or more computing devices each composed of well-known hardware components such as one or more processors coupled to network interfaces and storage devices. In an embodiment, a computing device further includes a virtualization component (e.g. hypervisor or virtual machine monitor) permitting a plurality of computing devices to share underlying physical hardware of the computing device. The one or more processors of server 140 execute various software components (e.g. computer executable instructions) loaded from non-transitory storage devices. By executing the software components, the one or more processors are configured to perform various functionalities on behalf of the remote clients.

In an embodiment, server 140 is a cloud-based server providing a shared pool of configurable computing resources to remote clients as a service. That is, server 140 may be implemented with a service-oriented architecture in which software components executing on hardware resources associate with server 140 provide services to other software components executing on remote devices (e.g. monitor device 130 and client device 160). Examples of such services provided by server 140 include infrastructure services, platform services, software application services, or a combination thereof. In an embodiment, any combination of interconnect data, interconnect metadata, and any other data corresponding to the interconnect signals propagating along common interconnect 120 is stored on server 140. In an embodiment, server 140 processes any combination of interconnect data, interconnect metadata, and any other data corresponding to the interconnect signals propagating along common interconnect 120 for client device 160's consumption.

Network 150 represents any communication network that enables computing devices to exchange data. Network 150 may include a combination of discrete networks that may use different communication protocols, but is depicted in simple form to not obscure other aspects of the present invention. For example, network 150 may be implemented using a cellular network, a WiFi/broadband network, a local area network (LAN), a wide area network (WAN), a telephony network, a fiber-optic network, the Internet, or a combination thereof.

Client device 160 represents a computing device that is adapted to exchange data with another computing device via network 150. Some lower-level details of client device 160 are not shown so as to not obscure embodiments of the present invention. For example, client device 160 may include a bus that directly or indirectly couples the following devices: memory; one or more processors; one or more presentation components such as a display or speaker; input/output (I/O) ports; I/O components; and a power supply such as a battery.

Client device 160 may take on any of a variety of forms. By way of example, client device 160 may be a mobile telephone, smart phone, laptop computing device, desktop computing device, server, tablet computer, personal digital assistant (PDA), or any other computing device. Client device 160 may be associated with a user. The user is the person submitting instructions and interacting with client device 160. Operational environment 100 may include any number of client devices. A single client device is shown for the sake of simplicity.

FIG. 2 depicts an operational environment for implementing aspects of the present invention is depicted and referenced generally by designator 200. For instance, base station 290 may implement methods 700 and 800 of FIGS. 7 and 8 , respectively. In an embodiment, the components of operation environment 200 operate in a similar manner as the components of operation environment 100 unless indicated otherwise.

In operational environment 200, base station 290, server 140, and client device 160 are configured to communicate data via network 150. In an embodiment, the event detectors (110A and 110B) as well as the monitor devices are incapable of communicating data via network 150.

Base station 290 and one or more monitor devices (e.g. monitor devices 130A and/or 130B) communicate data via communication links 295. In an embodiment, the one or more monitor devices are communicatively coupled via a communication link 295.

Base station 290, in general, serves as an end access point for remote clients (e.g. server 140 or client device 160) to consume information associated with interconnect data via network 150. In operational environment 200, a remote client establishes a communication session with a network interface of base station 290. Base station 290 and the remote client exchange communications regarding interconnect data within the communication session. For example, base station 290 may receive an alert instruction from a remote client within a communication session via the network interface. As another example, base station 290 may communicate a status report associated with one or more of the event detectors to the remote client within the communication session via the network interface.

Base station 290 receives information associated with interconnect data for remote clients to consume using data received from one or more monitor devices. Similar to monitor device 130 of FIG. 1 , the one or more monitor devices of operational environment 200 monitor interconnect signals propagating on a common interconnect coupling one or more event detectors. In an embodiment, the monitor devices analyze the interconnect signals propagating on the common interface and the data received by base station 290 is any combination of interconnect data and interconnect metadata.

In an embodiment, the one or more monitor devices do not analyze the interconnect signals propagating on the common interface and the data received by base station 290 is raw data representing the interconnect signals. In an embodiment, base station 290 generates any combination of interconnect data and interconnect metadata based in part on its own analysis of the raw data. In an embodiment, base station 290 generates any combination of interconnect data and interconnect metadata based in part on its own analysis of the raw data and secondary data received from a second monitor device (e.g. monitor device 130B). In an embodiment, base station 290 generates any combination of interconnect data and interconnect metadata based in part on its own analysis of the raw data and secondary data received from a sensor not associated with the one or more monitor devices.

In an embodiment, base station 290 provides computing resources to the one or more monitor devices. Examples of such computing resources include processing resources, communication resources, storage resources, or a combination thereof. For example, base station 290 may provide monitor device 130A with storage resources to store historical data associated with the interconnect signals propagating along the common interconnect. As another example, base station 290 may provide monitor device 130B with communication resources to directly communicate with client device 160 (or vice versa).

Responsive to detecting an event, controller 320 is configured to generate an interconnect signal indicative of the detected event. In an embodiment, controller 320 is configured to generate a plurality of unique interconnect signals with each unique interconnect signal among the plurality corresponding to a particular detected event.

Controller 320 forwards the interconnect signal to one or more alert indicators (e.g. alert indicator 330) to generate a sensory notification. In an embodiment, controller 320 is configured to select a particular alert indicator among the one or more alert indicators to forward the interconnect signal. Controller 320 is further configured to forward the interconnect signal via interface 340 to a common physical medium (e.g. common interconnect 120 of FIG. 1 ).

By forwarding the interconnect signal to the common physical medium, controller 320 enables at least one event detector to likewise generate a sensory notification to indicate detection of an event.

Alert indicator 330 is configured to generate the sensory notification in response to receiving an interconnect signal from controller 320. For example, event detector 110 may be a smoke event detector.

In an embodiment, alert indicator 330 is configured to generate a sensory notification in response to event detector 110 receiving an interconnect signal via interface 340. In an embodiment, alert indicator 330 is configured to generate a multi-sensory notification capable of being perceived by a plurality of the observer's senses. For example, a multi-sensory notification may be implemented as a combination of optical and acoustic waves. A sensory notification is characterized by one or more attributes, such as a frequency, a duty cycle, an amplitude, a periodicity, and the like. In an embodiment, a sensory notification includes a message component that provides specific information about a detected event. For example, if event detector 110 is a smoke event detector, the sensory notification may include a message component stating that smoke has been detected in the specific location of the smoke event detector. Continuing with this example, the message component may further provide routing information to enable an observer to identify a safe means of egress.

In an embodiment, processor 430 enables monitor device 130 to implement one or more functionalities described herein by executing such processor executable instructions. For example, processor 430 may execute processor executable instructions to instantiate one or more functionalities associated with analytics circuitry 440.

It should be appreciated by those skilled in the art that the functionality of monitor device 130 implemented through processor executable instructions may readily be converted into a hardware implementation by well-known design rules in the electrical engineering and software engineering arts. For example, the functionality of monitor device 130 described herein can be converted into a hardware implementation using application-specific integrated circuits, microcontrollers, field programmable gate arrays, digital signal processors, and the like. Those skilled in the art will likewise recognize that the functionality of monitor device 130 may readily be implemented through a hybrid approach composed of combination of hardware and software techniques.

Analytics circuitry 440 is generally configured to analyze data associated with interconnect signals obtained by monitor device 130 from a common interconnect. Analytics circuitry 440 includes data retrieval service 442, inference service 444, context service 446, and context service 448. In an embodiment, one or more of the functionalities of analytics circuitry 440 are implemented by at least one processor of a base station (e.g. base station 290 of FIG. 2 ). In an embodiment, one or more functionalities of analytics circuitry 440 are implemented by at least one processor of a remote server (e.g. server 140 of FIG. 1 or cloud-based server 900 of FIG. 9 ).

Data retrieval service 442 is configured to retrieve data associated with the interconnect signals as directed by processor 430, and provide such data to the other services of analytics circuitry 440 for further processing. In an embodiment, data retrieval service 442 retrieves at least a portion of the data from data store 420. In an embodiment, data retrieval service 442 retrieves at least a portion of the data from interconnect interface 410.

Inference service 444 is configured to receive input data associated with interconnect signals from data retrieval service 442, machine learning service 448, or a combination thereof and generate interconnect data. Inference service 444 outputs the interconnect data to a network interface via communication circuitry 450. In an embodiment, inference service 444 determines one or more characteristics of an interconnect signal associated with an event detector using input data received from data retrieval service 442. As used herein, “characteristics of an interconnect signal” refers to measurable physical properties of the interconnect signal. For example, measurable physical properties may include electrical properties (e.g. resistance, reactance, voltage, current, phase, resonant frequency, etc.) or observable patterns (e.g. a repeated sequence of changes in the electrical properties). For example, inference service 444 may compare a voltage associated with an interconnect signal at a current time to a voltage value associated with the interconnect signal at a prior time. As another example, inference service 444 may identify a repeated pattern of phase shifts associated with an interconnect signal.

In an embodiment, the input data from data retrieval service 442 includes information associated with the interconnect signals provided by a second monitor device (e.g. monitor device 130B of FIG. 2 ). Inference service 444 may generate interconnect data by comparing one or more characteristics of the interconnect signals from the information provided by the second monitor device with comparable information as measured by monitor device 130. For example, inference service 444 may compare a current value of an interconnect signal as provided by the second monitor device with a current value of the interconnect signal as measured by monitor device 130. Inference service 444 may generate interconnect data based on the results of that comparison.

In an embodiment, inference service 444 may generate interconnect data by applying information associated with an interconnect signal received from data retrieval service 442 as an input to a machine learned model received from machine learning service 446. For example, inference service 444 may input information associated with an interconnect signal at a current time from data retrieval service 442 into a machine learned model trained using previously obtained information associated with the interconnect signal. The machine learned model may generate interconnect data based on that input.

In an embodiment, the information output by inference service 444 is information about at least one event detector's alarm status. For example, inference service 444 may determine an event detector's alarm status is activated. That is, the event detector has detected an event associated with a physical environment proximate a location of the event detector. As another example, inference service 444 may determine an event detector's alarm status is inactivated. That is, the event detector has not detected an event associated with a physical environment proximate a location of the event detector.

In an embodiment, the information output by inference service 444 is information about at least one event detector's operational status. For example, inference service 444 may determine an event detector's operational status is fully functional. That is, inference service 444 may determine the event detector is functioning properly (e.g. the event detector is fully powered or substantially operating without apparent fault).

As another example, inference service 444 may determine an event detector's operational status is degraded. That is, inference service 444 may determine the event detector is functioning less than fully functional, but more than non-functional (e.g. the event detector is not fully powered or operating with apparent faults). As another example, inference service 444 may determine an event detector's operational status is non-functional. That is, inference service 444 may determine the event detector has ceased functioning (e.g. the event detector lost power or ceased operating).

In an embodiment, the information output by inference service 444 is identifying information about at least one event detector. As discussed above, examples of identifying information include the event detector's manufacturer, model number, configuration, and the like. For example, inference service 444 may compare one or more characteristics of an interconnect signal associated with an event detector at a current time with an interconnect signal associated with the event detector at a prior time.

As another example, inference service 444 may compare one or more characteristics of an interconnect signal associated with a first event detector at a current time with an interconnect signal associated with a second event detector. In an embodiment, the interconnect signal associated with the second event detector is from the current time. In an embodiment, the interconnect signal associated with the second event detector is from a prior time.

As another example, inference service 444 may compare one or more characteristics of an interconnect signal associated an event detector at a current time with a model interconnect signal. In an embodiment, the model interconnect signal is obtained from a machine learned model trained with historical data associated with the event detector. In an embodiment, the model interconnect signal is obtained from a machine learned model trained with historical data associated a plurality of event detectors. In an embodiment, the model interconnect signal is received via a network interface.

Context service 446 is configured to receive input data from data retrieval service 442, inference service 444, or a combination thereof and generate interconnect metadata. In an embodiment, context service 446 is configured to utilize a machine learned model received from machine learning service 448 to generate interconnect metadata. In an embodiment, context service 446 is configured to generate interconnect metadata by analyzing data collected from a plurality of devices (e.g. monitor devices, event detectors, etc.).

In an embodiment, context service 446 generates interconnect metadata using secondary data received from data retrieval service 442 in response to receiving interconnect data from inference service 444. For example, inference service 444 may generate interconnect data for an event detector (e.g. a smoke detector) at a current time. In this example, the interconnect data may indicate that the event detector's alarm status is activated (i.e. the event detector has detected an event proximate its location). Upon receiving the interconnect data, context service 446 acquires sensor data from a temperature sensor external to the event detector at a location proximate to the event detector at the current time. Context service 446 may generate interconnect metadata indicative of the sensor data associated with the interconnect data.

Continuing with this example, the sensor data from the temperature sensor may indicate that a temperature of the location is normal room temperature. Context service 446 may further generate a low confidence value upon receiving sensor data from a sensor external to the event detector that is inconsistent with the detected event. Context service 446 may generate interconnect metadata indicative of the low confidence value associated with the interconnect data. As another example, context service 446 may receive interconnect data generated by inference service 444 based in part on interconnect signals. Upon receiving the interconnect data, context service 446 acquires time stamp information from data retrieval service 442 to determine a current time. In this example, the sensor data from the temperature sensor may indicate that a temperature of the location is normal room temperature.

In an embodiment, context service 446 generates interconnect metadata using historical data received from data retrieval service 442 in response to receiving interconnect data from inference service 444. For example, context service 446 may receive interconnect data for an event detector at a current time from inference service 444. In response, context service 446 may acquire historical data associated with the event detector from data retrieval service 442. Upon analyzing the historical data associated with the event detector, context service 446 may determine that the previous events detected by the event detector were identified as false alerts. Context service 446 may generate interconnect metadata indicative of the event detector's history of false alerts associated with the interconnect data.

In an embodiment, context service 446 generates interconnect metadata directly from interconnect data received from inference service 444. For example, context service 446 may receive interconnect data for an event detector that indicates the event detector's alarm status is activated and operational status is degraded. In response, context service 446 may generate interconnect metadata indicative of the degraded operational status of the event detector for the interconnect data. In an embodiment, a reduced confidence score may be used to indicate the degraded operational status.

Machine learning service 448 is configured to train machine learned models using training data obtained from data sets composed of historical interconnect signal data received from data retrieval service 442. Once trained, the machine learned models may be used by inference service 444 and/or context service 446 to generate interconnect data and interconnect metadata, respectively. Machine learning service 448 may employ any known artificial intelligence, machine learning, knowledge-based, or rule-based mechanisms to train machine learned models. Examples of such mechanisms include support vector machines, neural networks, expert systems, Bayesian belief networks, fuzzy logic, data fusion engines, classifiers, and the like.

In training the machine learned models (e.g. find optimal values of for model parameters), machine learning service 448 may use an objective function to measure the performance of the models using a subset of the training data as a function of the model parameters. For example, optimal values of the parameters of a model may be determined by finding a minimum of the objective function. As another example, multiple iterations of a stochastic gradient descent procedure may be performed to find the optimal values of the parameters. In an embodiment, the machine learning model is composed of a single level of linear or non-linear operations. In an embodiment, the machine learning model is a deep network composed of multiple levels of non-linear operations. For example, the machine learning model may be a neural network with one or more hidden layers.

Examples of controlling mechanisms include programmable logic controllers, microcontrollers, distributed control systems, home automation hubs, and the like.

In an embodiment, control circuitry 470 exchanges data with a controlling mechanism in response to a command from a remote client received via a network interface. For example, a command may be received from a remote client (e.g. server 140 or client device 160 of FIG. 1 ) via a network interface to turn off a gas valve. The command may be received in response to transmitting interconnect data to the remote client that indicates a smoke detector's alarm status is activated. Upon receiving the command, control circuitry 470 may exchange data with a controlling mechanism associated with the gas valve thereby causing the gas valve to move to a closed position.

In an embodiment, control circuitry 470 exchanges data with a controlling mechanism in response to a command from processor 430, a second monitor device, a base station associated with monitor device 130, or a combination thereof. For example, a base station may receive interconnect data indicating that an event detector associated with an electrical power feed has detected a loss of power event. Upon receiving that interconnect data, the base station may send a command to activate an electrical generator. In response to that command, control circuitry 470 may exchange data with a controlling mechanism associated with the electrical generator to activate the electrical generator.

In an embodiment, cloud-based server 900 is used to implement at least a portion of server 140 in FIGS. 1 and 2 . The infrastructure services may include virtualized resources, such as virtual machines, virtual storage, and so on. The infrastructure services may also include virtualized services, such as database services and others. Each of these infrastructure services may be deployed in an infrastructure service layer 920.

The scale and various aspects, such as data, connectivity, and dependency relationships within and between service components, of an infrastructure service deployment are configurable by an administrator user. For instance, the administrator user may submit a configuration specification to cloud-based server 900 via a frontend interface 950 and service manager 960. The configuration specification can be translated into infrastructure and kernel level APIs calls that create, re-create, move, or delete components such as virtual machines and services, and assign or change attributes of the components.

Depending on the type of services, a cloud-service user may be granted different levels of control in configuring the services. For example, if a software application service is employed, an administrator user is given control over how the software application is configured. If a platform service is employed, an administrative user is given control over how the platform and/or application frameworks are configured. Similarly, if infrastructure services are employed, an administrative user is given control over the particular infrastructure services employed.

FIGS. 11-12 depict waveform diagrams of conventional interconnect signals propagated by event detectors on a common interconnect. FIG. 11 depicts an example of an interconnect signal 1100 propagated on a common interconnect by conventional smoke event detectors. A conventional smoke event detector generates an interconnect signal similar to interconnect signal 1100 in response to detecting a smoke event. As shown by FIG. 11 , interconnect signal 1100 transitions from a first voltage (e.g. 9 volts DC) to a second voltage (e.g. 0 volts DC) in response to detecting the smoke event. In response to sensing that transition from the first voltage to the second voltage, all conventional smoke event detectors coupled to the common interconnect will generate a sensory notification. Upon receiving an acknowledgement of the smoke event, interconnect signal 1100 transitions from the second voltage to the first voltage.

FIG. 12 depicts an example of an interconnect signal 1200 propagated on a common interconnect by conventional carbon monoxide event detectors. A conventional carbon monoxide event detectors generates an interconnect signal similar to interconnect signal 1200 in response to detecting a carbon monoxide event. As shown by FIG. 12 , unlike interconnect signal 1100, interconnect signal 1200 indicates detection of a carbon monoxide event with using a sequence of electrical pulses. In response to sensing that sequence of electrical pulses, all conventional carbon monoxide event detectors coupled to the common interconnect will generate a sensory notification. FIGS. 13A-13C depict various embodiments of aspects of a monitor device 130 as described above with respect to FIG. 4 . FIG. 13A discloses a circuit connected in parallel to common interconnect 120. In embodiments, the circuit of FIG. 13A has two portions as represented by the dashed line. The top portion is the detecting portion that detects a signal. The bottom portion is a signal injecting portion that injects a signal back onto common interconnect 120. The injected signal can emulate an event signal, e.g., a smoke detection event, or can inject another signal that is processed by the detecting portion to cause, e.g., the detecting portion to take some action such as to send out a signal over wireless transceiver 1306. In other embodiments, a monitor device may only have an event detecting portion and not an injecting portion. In other embodiments, a monitor device may only have an injection portion that monitors for signals incoming over wireless interface 1306 and outputs a signal on the common interconnect 120.

In an embodiment, a signal that is output onto common interconnect 120 by an event detector is received by input buffer 1312 a. Buffer 1312 a could be an isolation device such as optical isolation, buffer circuitry, analog or digital radio receiver and transmitter. The output from buffer 1312 a is input into signal translator 1308 a. Signal Translator 1310 a could be, for example, a voltage step up/down, radio mixer, an analog to digital convertor, or any other device that translates a signal received on the common interconnect 120 into a signal that can be processed by a signal analyzer 1302. Signal analyzer 1302 can be hardware, e.g., a gate array, or software operating on a processor, such as a digital signal processor. Signal analyzer 1302 determines whether the signal matches a known pattern. In response to determining that a signal matches a known pattern, signal analyzer 1302 can cause a signal to be output over wireless interface 1306. The signal output over 1306 may be a signal that indicates to other devices that an event was detected on a particular common interconnect 120.

In embodiments, another portion of the circuit of FIG. 13A comprises the signal injector portion of the circuit. The signal injector portion comprises a signal creator 1304. Signal creator 1302 could share some or all of the hardware of signal analyzer 1302. For example, they may both reside on the same processor. Signal creator 1304 outputs a signal that is translated by signal translator 1310 a. Signal translator may comprise, for example, a digital to analog converter, that outputs an analog signal that is processed by buffer 1314 a and injected back onto common interconnect 120.

In another embodiment, as shown in FIG. 13B, the circuit can be installed in series. In that case, buffer 1312 a would receive a signal arriving on one portion of the common interconnect 120 and process the signal as described with respect to FIG. 13A. In this embodiment, the common interconnect 120 is not continuous, e.g., it was broken during the installation of the circuit. In this embodiment, the could be a second portion of the circuit comprising, signal translators 1308 b, 1310 b, buffers 1312 b and 1314 b. In this configuration, a determination could be made regarding the direction of the signal received on common interconnect 120. Similarly, the direction that the signal is injected onto common interconnect 120 can also be controlled.

In another embodiment, the circuit could comprise passive components. An example embodiment is illustrated with respect to FIG. 13C. In that example embodiment, a series of, e.g., resistors 131 ba, 1318 b, and 1318 c are provided. The signal analyzer 1302 is connected between the resistors and can determine from which direction a signal is arriving. In addition to the foregoing configurations and embodiments, other embodiments may combine aspects of both passive and active components. For example, an active signal injector circuit may be combined with a passive signal detection circuit.
